Castello Aragonese di Baia
Built in a strategic place at the end of the fifteenth century by Alfonso of Aragon, it was part of a program for the construction of fortification systems that extended throughout Italy by Aragon. It is a large architectural complex of Roman origin. It has had times of abandonment, but now, thanks to the reconstructions, it is in excellent condition and works as a museum, with various archaeological objects, even very rare.
